[Qemu-devel] [RFC PATCH v1 0/3] spapr: Work around the memory hotplug failure with DDW

Memory hotplug can fail when upcoming, yet-to-be-upstreamed, 2.7 feature DDW is enabled. This happens due to a guest kernel bug which results in DDW code in QEMU obtaining incorrect value of max possible memory address. This incorrect max mem value results in incorrect DDW size which later causes

Memory hotplug can fail for some combinations of RAM and maxmem when DDW is enabled in the presence of devices like nec-usb-xhci. DDW depends on maximum addressable memory returned by guest and this value is currently being calculated wrongly by the guest kernel routine memory_hotplug_max(). While
